Rotary Connection, formed in Chicago in 1966, was a pioneering psychedelic soul band that seamlessly blended rock, soul, and orchestral elements. Under the visionary direction of Marshall Chess and arranger Charles Stepney, the group featured the remarkable vocals of Minnie Riperton, who later achieved solo fame. Their innovative sound is showcased in albums like their self-titled debut and "Peace," a Christmas release with strong messages of love and understanding during the Vietnam era. Notably, they collaborated with blues legends Muddy Waters and Howlin' Wolf on their experimental albums "Electric Mud" and "The Howlin' Wolf Album," respectively. Rotary Connection's genre-defying approach left an indelible mark on the music landscape. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Rotary_Connection?utm_source=openai))
